The Silica Gel Set 8-Pack from BRNO will help minimize condensation buildup in your camera's lens and other parts. This is important for preventing any moisture damage to your camera. In climates with heavy changes in temperature or even when moving from cold air conditioning into a hot humid environment, condensation can form. Orange silica gels turn green when they need to be replaced, helping you to stay on top of your moisture protection. This 8-pack will help you keep your camera and its parts at the optimum relative humidity (RH) of 35% to 45%.
